The Formal Theorem

S = ax^3 + bx^2 + cx + d

Analytical Intuition.

Cubic Splines are Mathematical Ribbons. Connecting data points with perfectly smooth curves. Visually flexible drafting rulers pinned to points. Prevents high-degree oscillations.
CAUTION

Institutional Warning.

Boundary conditions define the final flow. Natural splines have zero end curvature.
